What is wrong with people? Modern trends point toward the increase of social interaction via computers. People spend many hours typing to their friends and acquaintances, so why the hell can people not spell.
My personal button is the confused use of 'weather' and 'whether' and 'there' and 'their'. When I read posts or tech’ specs / explanations, I simply cannot take the advice given seriously. A misspelling makes me think 'yeah, that was written by a 12 year old'.
I even read 'their' in place of 'there' in a newspaper the other day. You write for a living, at least use a blinking spell checker, and editors do your job.

The solution is this, ‘leet speak’ has become quite socially unacceptable, and to such a degree that people do not use it anymore unless they are a true idiot or are taking the mick. The use of this deformity of language has been eroded by constant snipes at the users. I think if people can be embarrassed into using proper spelling, eventually the correct spelling will be learned and we won't see the gradual decline of the language through digital social networking.
I frequently just get annoyed at those who misspell and say nothing; I propose that all those who do get annoyed at this should point it out to posters (in a nice way) and correct the mistake.
